[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, a cutting head height sensor module provided by an embodiment of the present application comprises a height sensor 1 provided with a No. 1 through hole, a ceramic body 2 provided with a No. 2 through hole and abutting against the lower end of the height sensor 1, a copper nozzle 3 provided with a No. 3 through hole and threadedly connected to the ceramic body 2, wherein the No. 1 through hole, the No. 2 through hole and the No. 3 through hole are connected in sequence to form a light outlet hole, and the ceramic body 2 is provided with a No. 1 step 21. It also comprises a ceramic locking ring 4, a stainless steel ring 7 provided with an external thread, and a plurality of set screws 5, wherein the ceramic locking ring 4 comprises an annular plate 41 and an annular cylinder 42 provided on the outer periphery of the annular plate 41, wherein the upper end surface of the annular plate 41 abuts against the No. 1 step 21, the annular cylinder 42 is provided with an internal thread threadedly connected to the stainless steel ring 7, the stainless steel ring 7 is provided with a plurality of screw holes extending radially in the circumferential direction, and the screw holes are located above the external threads, the height sensor 1 is provided with a groove 10 corresponding to the screw, and the set screw 5 abuts against the groove 10 after being threadedly connected to the screw hole.

[0019] In actual use, when the copper nozzle 3 collides with an external object during the cutting process and the ceramic locking ring 4 needs to be replaced, the set screw 5 is removed to disengage the stainless steel ring 7 from the height sensor 1. Since the stainless steel ring 7 is threadedly connected to the ceramic locking ring 4, when the stainless steel ring 7 is not connected to the height sensor 1, the ceramic locking ring 4 is also disassembled together with the stainless steel ring 7, so that the annular plate 41 loses contact with the first step 21, thereby causing the ceramic body 2 to lose connection with the height sensor 1. The disassembly of the ceramic body 2 is completed.

[0020] In the above design, the design of the stainless steel ring 7, the locking screw 5 and the ceramic locking ring 4 makes it possible to easily disassemble and replace the ceramic body 2 even if the locking thread of the ceramic locking ring 4 is deformed when the laser cutting head is hit, thereby reducing the equipment downtime and maintenance costs.

[0021] Specifically: Figure 2 As shown, the lower end surface of the height sensor 1 is provided with a circular groove for mounting the ceramic body 2, and the lower end of the height sensor 1 is provided with an annular groove concentric with the No. 2 through hole, and a No. 1 sealing ring 6 is provided in the annular groove.

[0022] In actual use, the gap between the height sensor 1 and the ceramic body 2 is isolated by the No. 1 sealing ring 6 .

[0023] In the above design, the stability and convenience of the installation of the ceramic body 2 can be effectively guaranteed, and the sealing between the height sensor 1 and the ceramic body 2 can be effectively guaranteed.

[0024] Specifically: Figure 3 As shown, the groove 10 is a conical groove.

[0025] In actual use, the end of the set screw 5 extends into the conical groove.

[0026] In the above design, setting the groove 10 as a conical groove can effectively ensure the fixation of the end of the set screw 5.

[0027] Specifically: Figure 1 As shown, a vertical groove 401 is circumferentially arranged on the outer side of the ceramic locking ring 4 .

[0028] In actual use, the ceramic locking ring 4 and the stainless steel ring 7 are locked by manually rotating the outer side of the ceramic locking ring 4 .

[0029] In the above design, the roughness of the outer side of the ceramic locking ring 4 is increased by providing the vertical groove 401, thereby facilitating manual screwing of the ceramic locking ring 4.

[0030] Specifically, the first through hole, the second through hole and the third through hole are all contracted downward.

[0031] In the above design, it is convenient for the laser to cut through the No. 1 through hole, the No. 2 through hole and the No. 3 through hole.

[0032] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
